Answer:
Option-A
Explanation:
In the given question, the artificial ecosystem was prepared by the scientist which included the animals and plants. The light and dark conditions were controlled by a switch and bulb.
In the beginning, the amount of Carbon in the form of carbon dioxide was low due to the utilization of carbon dioxide by plants to perform photosynthesis. Then the amount of carbon dioxide increased in the atmosphere, the reason could be due to less consumption of carbon dioxide. The carbon dioxide is not uptake by plants during night conditions when photosynthesis process slowed down or stops.
Therefore, the dark condition was created by the scientist by switching off the lights and the number of energy molecule decreased as no photosynthesis was occurring.
Thus, Option-A is the correct answer.

Answer: emergent properties at molecular level
Explanation:
Enzyme is a globular protein, the condensation of amino acid units involved bond interactions of the non-polar, hydrophobic R group which pointed away from the watery environments towards the the center of the molecule.
The hydrophilic R groups point to the watery environments. This arrangement ensured solubility. Besides, the bond interaction and inter molecular forces during the interaction of amino acids bonds making and breaking in tertiary structure of protein gave enzyme the three dimensional structure for the precise active sites for enzymatic reaction.
<u>Therefore emergent properties refereed to the new properties acquired by a complex compound or macro- molecules from the bonding or condensation of its smaller units,molecules,or monomers. </u>
These new properties were not present in individual smaller units, in this case amino acids, before bonding.
Answer:
1. C. Anaphase I 2. A. Prophase I 3. D. Telophase I 4. A. Prophase I
Explanation:
All of these questions deal with the four phases of cell division. Let's figure out what happens in each phase.
Prophase: This is the first stage of cell division, where the chromosomes become visible and the nuclear envelope disappears. In this phase, the cell is preparing the separate.
Metaphase: This is the second stage of cell division. Spindle fibers attach to the chromosomes in order to separate them.
Anaphase: This is the third stage. The chromosomes are pulled away from each other towards opposite sides of the cell
Telophase: This is the last stage of cell division. The chromosomes have reached the opposite sides of the cell and now the nuclear envelope is reforming around the now separated chromosomes and two separate cells are formed.
